Colossal Structures Discovered Towering Above Saturn's Rings

Saturn.rings.vertical This one is a 10 on the Galaxy wow meter: In images made possible only as Saturn nears equinox, NASA's Cassini spacecraft has uncovered for the first time towering vertical structures in the planet's otherwise flat rings that are attributable to the gravitational effects of a small nearby moon.

The search for material extending well above and below Saturn's ring plane has been a major goal of the imaging team during Cassini's "Equinox Mission," the two-year period when the sun is seen directly overhead at noon at the planet's equator. This novel illumination geometry, which occurs every half-Saturn-year, or about 15 Earth years, lowers the sun's angle to the ring plane and causes out-of-plane structures to cast long shadows across the rings' broad expanse, making them easy to detect.

In recent weeks, Cassini's cameras have spotted not only the predictable shadows of some of Saturn's moons, but also the shadows of newly revealed vertical structures in the rings themselves. And these observations have lent dramatic support to the analysis presented in today's publication that demonstrates how small moons in very narrow gaps can have considerable and complex effects on the edges of their gaps, and that such moons can be smaller than previously believed.

"We thought that this vertical structure was pretty neat when we first saw it in our simulations," said John Weiss, the paper's lead author and a research associate of Cassini imaging team leader Carolyn Porco, another co-author on the paper, in Boulder, Colo. "But it's a million times cooler to have your theory supported by such gorgeous images. It makes you suspect you might be doing something right."

Sounds interesting, Now if you were checking out the Planets closer to Earth instead of a planet so far away. maybe just maybe we'd be putting a civilization on it. Thats my feeling on this subject. Now if you still need money for future exploration, i still have a patent for an invention that worth more that $2 Trillion dollars. have a nice day. MIKE

Dear Mike,
Dont be an idiot.

offf post good
